NCT03831113

Brief Summary

This study is a pharmacodynamic study in pregnant women evaluating the relationship between buprenorphine concentration and outcome such as opioid withdrawal symptoms , NAS scores, neurodevelopmental and neuroanatomic outcomes. Strategies to reduce opioid exposure will be explored. There are 4 specific aims but only specific aim 4 is a clinical trial and reported here. In specific aim 4, eligible consenting women on buprenorphine in an MAT clinic will be assigned to 2 dose reduction regimens and their response to dose reduction will be measured using a visual analog scale.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale (VAS) Scores

    The VAS questionnaire consists of 4 questions related to cravings (0 = not at all to 10 = very much), withdrawal (0 = no symptoms to 10 = symptoms all day), sleep quality (0 = best to 10 = worst), and sleep duration (0 = longest ever to 10 = shortest ever). The 4 component questions are summed to provide a single VAS score for that day. The daily scores are averaged over the week or for two weeks depending on how often the dose was changed. The average VAS scores for each reduction regimen are averaged and compared to the alternative dosing group.

    36 weeks

Study Arms (2)

Magnitude Group

ACTIVE COMPARATOR

Subjects will receive alternating reductions of 1 mg or 2 mg weekly.

Drug: Magnitude Group

Frequency Group

ACTIVE COMPARATOR

Subjects will receive dose reductions of 2 mg on alternating intervals of 1 and 2 weeks.

Drug: Frequency Group

Interventions

Dose reductions will alternate between 1mg or 2 mg weekly until the subject is no longer taking buprenorphine or is at the lowest tolerable dose.

Also known as: magnitude
Magnitude Group

Dose reductions of 2 mg will occur alternate between once weekly to biweekly until the subject is no longer taking buprenorphine or is at the lowest tolerable dose.

Also known as: frequency
Frequency Group

Eligibility Criteria

Age18 Years - 45 Years
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsPregnant women who have been prescribed buprenorphine by a Medication Assisted Treatment (MAT) clinic.
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • On a stable dosing regimen of BUP for at least 2 weeks as part of an established medication- assisted treatment (MAT) program.
  • Willingness to undergo supervised dose reduction
  • Subject willingness to be assigned to either the Magnitude, or Frequency group.
  • Single gestation between 14-30 weeks at the initiation of the dose reduction
  • On a BUP dose between 6- 24 mg daily (lower doses will not provide sufficient data points)
  • Willingness to have urine samples tested for drugs of abuse and blood samples tested for BUP+M concentrations during the Medical Supervised Withdrawal (MSW) clinic appointments
  • Willingness to attend weekly or biweekly MSW clinic appointments and to have daily contact via text messaging and to complete daily logs of sleep quality, withdrawal symptoms and symptoms of craving.
  • Willingness to attend psychosocial support meetings as needed.

You may not qualify if:

  • Current incarceration
  • Lack of a phone or transportation to and from clinic
  • Major fetal malformation
  • Mother with significant vaginal bleeding or serious medical or obstetrical complication that could adversely affect the study
